Answer:
❤️Dude ❤️ I am just explaning See the process and do the number by yourself....❤️❤️
Step-by-step explanation:
If you happen to know the distance around the rectangle, which is its perimeter, you can solve a pair of equations for L and W. The first equation is that for area, A = L ⋅ W, and the second is that for perimeter, P = 2L + 2W.
stay home stay safe ❤️❤️❤️❤️❤️❤️

Answer:
Base = 14 Height=4
Step-by-step explanation:
The base is represented by (x+5) and the measure of its height by (x-5)
So the area will be
(x+5)(x-5)=56
x^2 - 25 = 56
x^2 = 56 + 25 = 81
x^2 = 81
x = 9
The base is (x+5 )=(9+5)=14
The height is (x-5)=(9-5)=4
Base = 14 Height=4
