M<A + m<B = 180
5y + 9y + 68 = 180
14y + 68 = 180
14y = 180 -68
14y = 112
y = 112/14
y = 8
so
m<B = 9y + 68
m<B = 9(8) + 68
m<B = 72 + 68
m<B = 140

The expressions for the width, W, and area, A, of the rectangle in terms of L are:
- W = - L
- A =
The expression for the perimeter of a rectangle is given as:
P = 2(L + W)
where L is its length and W its width
a. Given that the perimeter of the rectangle is 13 feet, then;
13 = 2(L + W)
divide through by 2
= L + W
So that;
W = - L
The required formula for the width as a function of L is: W = - L
b. Area of a rectangle can be expressed as;
A = L * W
substitute the expression for width in that of area to have
A = L * ( - L)
= L -
A =
The expression for the area A is: A =
