Question

Find the atea of the rhombus whose base =2.5and height=13.2

Answer 1

is the base and height in units on a graph

Answer 2

The area formula of a triangle is related to the area formula of a rectangle. Recall that the area of a rectangle can be determined by multiplying the length and width or the base and height.



If the rectangle is cut in half, we know have a triangle. So the area would be half the area of the rectangle.



Let's use the formula in some examples.

Ex. 1) Calculate the area of the triangle.



Ex. 2) Calculate the area of the triangle.



Ex. 3) Determine the area of the triangle.



Ex. 4) The area of the triangle is 32 cm2. Determine the height.



To help visualize what this problem is asking, draw the other half so that it forms a rectangle.




This rectangle would have an area of 64 cm2.

A = bh

64 = 10(x)



x = 6.4 cm
