Question 1

1.

Which equation can be used to find the area of this rectangle?

20 + 12 = A 

20 + 20 + 12 +12 = A 

(20 x 2) + ( 12x 2) =A 

20 x 12 = A 

Question 2

2.

The area of this shape is 24 square units. Select all the statements that are true about the area.

The area can be found by counting the number of squares that touch the edge of the shape.

The area can be found by multiplying the sides lengths that are 6 units and 4 units.

The area can be found by counting the grid squares inside the shape.

It takes 24 grid squares to cover the shape without gaps and overlaps.

The area can be found by adding  4×3 and  6×2

Question 3

3.

Priya decomposed a square into 16 smaller, equal-size squares and then cut out 4 of the small squares and attached them around the outside to make the new figure shown.
How does the area of the new figure compare with that of the original square?

The area of the new figure is greater.

The two figures have the same area.

We don’t know because neither the side length nor the area of the original square is known.

The area of the original square is greater
