Question

What is the length of 8:am

Answer 1

Let the breadth of the rectangle be x m. Then,

length of the rectangle =(2x−8) m

Given, perimeter =56 m

⟹2(2x−8+x)=56

⟹2(3x−8)=56

⟹6x−16=56

⟹6x=56+16[Transposing−16toRHS]

⟹6x=72

⟹x=12

Therefore, breadth of the rectangle =12 m and length of the rectangle =2×12−8=16 m
