You can write the dimensions of the rectangle as (x + 2) and (x - 5), and because the area is base × height, you can multiply the brackets together and make it equal to 56:
(x + 2)(2x - 5) = 56
2x² + 4x - 5x - 10 = 56
x² - x - 10 = 56
Now because you have an x², you need to make the equation equal to 0 so you can factorise, so:
2x² - x - 10 = 56
- 56
2x² - x - 66 = 0
(x - 6)(2x + 11)
So x is 6, because the other option is -5.5 and you cannot have a negative length.
I hope this helps!
The answer is 2.16 because 12.62 + 0.34 = 12.96 then 12.96 divided by 6 = 2.16 (please make me brainlyest)
Ok
A=bh
plug in
126 square meters=6b
126/6 6/6
21=b
base length=21meters
