Exercise 5 Page 442

Calculate the height of the rhombus by dividing the area by the base.

15 mm

Practice makes perfect

The area of a rhombus is the product of its base and its height. In our rhombus, we know that the base is 25 millimeters and the area is 375 square millimeters. Let's draw a diagram to help us visualize this shape.

We can substitute these values into the formula for the area of a rhombus and simplify.

A=bh

b= 25, A= 375

375= 25h

.LHS /25.=.RHS /25.

375/25=25h/25

Calculate quotient

15=h

Rearrange equation

h=15

The height of the rhombus is 15 millimeters.
