If the base of a triangle is increased by 50% and its height is decreased by 50%, then what will be the effect on its area?
Question 1:
If the base of a triangle is increased by 50% and its height is decreased by 50%,
then what will be the effect on its area?
A.
50% decrease
B.
75% decrease
C.
25% decrease
Feedback
Area of triangle = (1/2) * base * height
So effect on area = +50 + (-50) + (50)(-50)/100 = -25%
D.
25% increase

How many spherical balls whose radius is half that of cylinder can be formed by melting a cylindrical iron rod whose height is eight times its radius?
A cone of radius 12 cm and height 5 cm is mounted on a cylinder of radius 12 cm and height 19 cm.
Find the total surface area of the figure thus formed.
A cylinder and a cone have equal base and equal height. The ratio of the radius of base to height is 5 : 12.
Find the ratio of the total surface area of the cylinder to that of the cone.
The area of the inner part of a cylinder is 616 sq. cms and its radius is half its height. Find the inner volume of the cylinder.
A rectangular sheet of 0.5 cm thickness is made from an iron cube of side 10 cm by hammering it down. The sides of the sheet are in the ratio 1 : 5.
Find the largest side of the sheet.
A rectangle whose sides are in the ratio 6 : 5 is formed by bending a circular wire of radius 42 cm.
Find the largest side of the rectangle.
If the base of a triangle is increased by 50% and its height is decreased by 50%,
then what will be the effect on its area?
The sides of a triangle are in the ratio 3 : 4 : 5 whose area is 216 sq. cm.
What will be the perimeter of this triangle?
The perimeter of a rectangular plot is 340 m. Find the cost of gardening 1 m broad boundary around it at the rate of Rs 10 per sq. m.
The length and the breadth of a rectangular door are increased by 1 m each and due to this the area of the door increased by 21 sq. m. But if the length is increased by 1 m and breadth decreased by 1 m, area is decreased by 5 sq. m.
Find the perimeter of the door.
