Question

The perimeter of a rectangle is 54 cm. The area of the same rectangle is 176 cm². What are the dimensions of the rectangle?

Answer 1

11 cm by 16 cm
8 cm by 22 cm
5.5 cm by 32 cm
4 cm by 44 cm

Answer 2

2(l+b)=54
l*b=176
b=27-l
l(27-l)=176
27l-l^2-176=0
l^2-27l+176=0
l^2-16l-11l-176=0
l(l-16)-11(l-16)=0
(l-11)(l-16)=0
l=11 or 16 b=16 or 11
so option A
