Answer 1

45 squared units

Explanation:

So we know that the width of the rectangle is 3 units, and that the length of the rectangle is 5 times greater than the width. With simply maths we can find that the length we use the equation 3 multipled 5 = 15.

So we now know the length of the triangle is 15 units, so to find the area of a rectangle the equation would be: Length times width

3 units multiped by 15 units = x

x = 45 squared units

Answer 2

45

Explanation:

Since 5 x 3 is 15, 15 x 3 = 45
