Question

The length of a rectangle is twice its width. The perimeter is 60 ft. Find its area.

Answer 1

Step-by-step explanation:

$\Huge\underline{\underline{\sf ANSWER}}\\ length = 2 \times width \\ l = 2 \times w \\ \\ perimeter = 60 \\ 2(l + w) = 60 \\ 2(2w + w) = 60 \\ 3w = 30 \\ w = 10 \: cm \\ \\ l = 2 \times w \\ l = 20 \: cm\\ \\ area = l \times w \\ \: \: \: \: \: \: \: \: \: \: = 20 \times 10 \\ \: \: \: \: \: \: \: \: \: \: = 200 \: sq \: cm$

Answer 2

Answer:

2(l+b)=600ft

2(3x)= 60*254/100

6x=254*6/10

x=25.4

2x=50.8

area = l*b

254/10*508/10

129032/100

=1290.32cm^2
