Plug in 2 wherever you see 'a'

3(2) + 5(2)(2)

1. 3×2 = 6, so:

6 + 5(2)(2)

2. 5×2=10, 10×2=20, so:

6 + 20

The final answer is 26.

The sides of a rectangle are in the ratio 5 : 4. If the perimeter of the rectangle is 360 cm , find its area

djverab [1.8K]

Answer:

Step-by-step explanation:

let, the length is z

thus the ratio will be 5z : 4z

perimeter = 2 (a + b)

360 = 2 ( 5z + 4z )

180 = 9z

z = 20 cm

length = 100 cm and width = 80cm

area = length * width

area = 100*80

area = 8000cm²
