Answer:
The required option are
Length = 4 and width = x+5
Length = 2 and width = 2x+10
Step-by-step explanation:
Area of the rectangle = Length × width
Given
Area = 4x+20
Factoring out the common terms
Area = 4x + 4(5)
Area = 4(x+5)
Length = 4 and width = x+5
This can also be written as
Area = 2(2x+10)
Length = 2 and width =2x+10
A=bh/2
h=2A/b
h=2*175/16
h=21.875
h^2=s^2-(b/2)^2
h^2=s^2-b^2/4
h^2=(4s^2-b^2)/4
4h^2=4s^2-b^2
4s^2=4h^2+b^2
s^2=(4h^2+b^2)/4
s=√((4h^2+b^2)/4), since h=21.875 and b=16
s=√542.515625
s≈23.3 ft
