Perimeter of rectangle = 2*l+b. Area = l*b. If l = 1m, b = 55cm. Find area and perimeter

Answer 1

perimeter = twice length + twice width
L = length = 1
b = .55 meter

2 * 1 + b = 2 L + 2 w

so b = 2 w and w = .55/2 = .275

area = L w = 1 * .275 = .275 m^2

perimeter = 2*1 + 2*.275 = 2+.55 = 2.55 m
