Question

The ratio of areas of rectangle and a square is 3: 4.if perimeter of each is 40 units. find the dimensions of the rectangle.

Answer 1

Step-by-step explanation:

let length of square is l then

l=10 .

let the dimention of rectangle is m and n.

Perimeter =2(m+n)=40

so m+n =20 (1)

area rectangle /area square=3/4

mn/100=3/4

so m=75/n.

replacing value in first .

after that solve it
