Perimeter and Area
A square has a length of 12ft. What is the area and perimeter? Remember to label.
p = 48ft
a = 144ft2
2x + 3 = x
x = -1
13 + x < 4
x < -9
3x + 2 + 5(x - 1) = 8x + 17

A rectangle has a length of 5ft and a width of 15ft. Find the area and perimeter (remember to label)
a = 75ft2
p = 40ft
5b - 4b = 6b - 10
b = 2
(2/3)x > 4; solve the equation and tell three numbers x could equal
x > 6
10z + 4 = 2(3z + 8) - 12
z = 0
Solve for x
3/7 = x/147
x = 63
A triangle has a base of 8in, a slant of 12in and a height of 9in. Find the area and perimeter. Remember to label.
p=29in
a=72 in2

The area of a triangle is 144ft2. The height is twice the base. Find the base and height. Remember to label.
Base = 12ft
Height = 24ft
The length of a shape is 2x + 10 and the width is x. The perimeter is 35 + x. Write an equation then find the value of x and the area.
35 + x = 2x + 10 + 2x + 10 + x + x
x = 3
a = 78
