Question

A wire of length 150

inches is bent into a rectangle. If the length of the rectangle is 5
inches less than thrice its breadth, then answer the following:

Answer 1

breadth= 18.75 inches

length= 56.25 inches

Explanation:

if the breadth = x inches

length = 3x inches

perimeter of rectangle= 2(l+b)= 2(3x+x)= 2(4x)= 8x

we know that perimeter = 150inches

so x= 150/8= 18.75

breadth= 18.75 inches

length= 518.75x3 =6.25 inches
