Question

Skip-count to find the unknown area. Write a multiplication sentence for each tiled rectangle. You can use any color below to complete each tile.

Answer 1

Answer:

$(a)$ $Length= 3cm$   $Width = 6cm$   $Area = 24cm^2$

$(b)$ $Length= 3cm$   $Width = 8cm$     $Area= 24cm^2$

Step-by-step explanation:

Given

See attachment for rectangle

Solving (a):

From the first rectangle, there are 6 columns and 3 rows.

This implies that:

$Length= 3cm$

$Width = 6cm$

So, the area is:

$Area = Length * Width$

$Area = 3cm * 6cm$

$Area = 18cm^2$

Solving (a):

From the first rectangle, there are 3 rows and the total area is 24.

This implies that:

$Length= 3cm$

$Area= 24cm^2$

Area is:

$Area = Length * Width$

$24cm^2= 3cm * Width$

Make Width the subject

$Width = \frac{24cm^2}{3cm}$

$Width = 8cm$
