Question

The respective ratio between length and breadth of rectangle 5:3 the perimeter of the rectangle is 112m what is the measure of the base of tariangle whose height is equal to the length of rectangle and its area is equal to area of the rectangle

Answer 1

first half the perimeter, 112/2= 56
then ratio in no is = 56/8 =7
then to find length = 7*5 = 35
breath = 7*3 =21
area of rectangle = 35*21 =735
given = Area of rectangle is equal to Area of triangles.
length of rectangle is also equal to height of triangle
area of triangle = 1/2*base * height
1/2*base* 35 = 735
base = 735*2 / 35. = 42ans
