Question

Work out the area of a rectangle with base, b = 40mm and perimeter, P = 88mm

Answer 1

Answer:

Base = 40mm

Perimeter = 88mm

2 ( l + b ) = 88

2 ( l + 40 ) = 88

l + 40 = 88/2 = 44

l = 44 - 40 = 4

   

Length = 4

Area = l * b

        = 4 * 40

        = 160mm²

Therefore, area of the rectangle is 160mm².

Answer 2

Answer:

Answer:

Base = 40mm

Perimeter = 88mm

2 ( l + b ) = 88

2 ( l + 40 ) = 88

l + 40 = 88/2 = 44

l = 44 - 40 = 4

   

Length = 4

Area = l * b

       = 4 * 40

       = 160mm²
