Let’s Recall (Review)

Find the area of the irregular figure.

1. 2

Let’s Understand (Study the Concept)

Let us study the problem.

Lesson 2: Finds the area of triangles, parallelograms and

trapezoids using sq. cm and sq. m (M4ME - IVb -58)

RJ has a triangular shaped lot that is shown below. What is the area of the

RJ’s lot?

We have to use the formula:

Given:

b = 10m

h = 7m

A =

2

1

(b x h)A =

2

1

(10m x 7m)

A =

2

1

(70m)

A = 35m2

Therefore, the area of the triangular lot is 35m2

.

Let’s Apply

Find the area of triangle, trapezoid and parallelogram.

1. Find the area of a trapezoid with bases 12cm. and 6cm. and a height of 5cm.

2. Find the area of trapezoid with bases 17m and 19m and a height of 2m.

3. Find the area of triangle with a base of 2m and a height of 10m.

4. Find the area of triangle with a base of 6cm and a height of 15cm.

5. Find the area of parallelograms with a base of 13m and a height of 6m
