Answer: 75 square
Explanation:
Width is X
Length is 3x
Every rectangle has 2 equal widths x 2 equal lengths
Perimeter is 2x + 2(3x) = 40
X = 5
Width is now 5in
Length is now 15in
Area is 75in^2
Half of a perimeter is length + width, which equals to 20in
4x = 20, CX = 5
= 75 sq

Answer:
a) 3x-5=16
b) 30cm
Step-by-step explanation:
a) 5(x-1)=2(x+8)
5x-5=2x+16
5x-2x-5=16
3x-5=16
b) solving the equation gives x=7
put x=7 into first line, 5(7-1)=30cm
to check we can place it into second one as well
2(7+8)=30cm
