Question

Math 4 DIRECTIONS : Read the following problems and answer the questions that follow in your notebook. 1. The Grade Four pupils have a garden in the shape of a trapezoid. One side is 20 m long while the other side is 18 m long. The distance between the sides is 25 m. What is the area of the garden? What is asked? What are the given facts? What is the formula? What is the number sentence? What is the answer?

Answer 1

Explanation:

trapezoid's S1 = 20m

S2 = 18m

distance between the sides, i.e. height of the trapezoid, h = 25m

1.

area of the garden = area of a trapezoid =

(S1 + S2) / 2 * h

2.

area of a garden is asked which is in the shape of a trapezoid so we have to calculate the area of a trapezoid.

3.

the given facts are the length of two sides as well as the distance between the sides which will be considered as the height.

4.

formula to find the area of a trapezoid, = (a+b) / 2 * h

where a, b are the two sides and h is the height

5.

number sentence = (20 + 18) / 2 * 25

= 38 / 2 * 25

= 19 * 25

6.

answer is 475 m²
