Rectangle is 5 times the width the peremeter is 120 find its area
1 answer:
Answer:
Area=275cm²
Step-by-step explanation:
length=5cm
let W represent width
Perimeter=2(L+W)
120 =2(5+W)
120 =10+2W
Group like terms
120-10=2W
110=2W
Divide both side by the co-efficient of W which is 2
110/2=2W/2
55 =W
therefore width=55cm
Since we have got the length and the width we can find the area
Area of a rectangle=length×width
=5cm×55cm
=275cm²
