Area

I will find the area of triangles, special quadrilaterals and polygons in solving

real-world and mathematical problems.

Step by Step Practice

Area of a square is length x width Or Because the sides are the same length, side squared.

where

The area of the square is 121 units squared

What is the area of the square?

A square has all 4 sides the same length.

Step by Step Practice

This figure is made up of 6 triangles all with the same base and height.

Since there are 6 of these triangles 6 x 77 = 462 The area is 462 inches squared.

Find the area of the regular hexagon below by using the area formula for triangles.

The area of a triangle is base x height divided by two.

Step by Step Practice

This length is for both triangles but they are the same triangle, so divide 8 by 2 because of the two triangles. The base of the triangle is 4.

There are two triangles with this area, so 12 x 2 = 24.The area of a rectangle is length times width. 7 x 6 = 42Add the two areas. 24 + 42 = 66

If x = 15 units, y = 7 units, and h = 6 units, then what is the area of the trapezoid shown below?

The area of a triangle is base x height divided by two. The area of a rectangle is length times width.

Step by Step Practice-Check Yourself

What is the area of the object below?2 x 7 = 144 x 12 = 48 14+48 6262

Step by Step Practice-Check Yourself

If x = 9 units, y = 4 units, and h = 3 units, then what is the area of the parallelogram shown below?9 x 3 = 27

27

Step by Step Practice-Check Yourself

If x = 11 units and h = 4 units, then what is the area of the triangle shown below?
