Exercise 10 Page 338

The area of a parallelogram is the product of its base and its height.

12m

We are told that the base of the parallelogram is 13 meters and that its area is 156 m^2. We want to find the height h. Let's draw a diagram to illustrate the situation.

We know that the area of a parallelogram is the product of its base and its height. A= b h We can substitute A= 156 and b= 13 into this formula and solve for h, the height of the parallelogram. Let's do it!

A=bh

A= 156, b= 13

156= 13* h

▼

Solve for h

.LHS /13.=.RHS /13.

156/13=13h/13

Calculate quotient

12=h

Rearrange equation

h=12

We found that the height of the parallelogram is 12 meters.
