Answer:
Length = 18m, Width = 6m, Area = 108m²
Step-by-step explanation:
Let,
Width = x , Length = 3x
Perimeter of a rectangle = 2(length + width)
= 48m = 2(x + 3x)
= 2(x + 3x) = 48m
= 2 × 4x = 48m
= 4x = 48/2
= 4x = 24
= x = 24/4 = 6
∴ x = 6
therefore,
Width = x = 6m
Length = 3x = (3 × 6)m = 18m
Also,
Area of a rectangle = LENGTH × WIDTH
=(6×18)m² = 108m²
∴ Area = 108²
Hope it helps :)
