A rectangle has an area of 90 square centimeters and a height of 12.5 centimeters. What is the length of the base?
Sergio [31]

Answer:

A. 7.2 centimeters

Step-by-step explanation:

The length of the base is 7.2 centimeters. The area of a rectangle is length*width

The length is unknown but the area is known. To find the length, all we have to do is divide the area from the height.

The working is as follows :

Area = 90 cm²

Height = 12.5 cm

Length = ?

<em>Length</em><em> </em><em>=</em><em> </em><em>Area</em><em> </em><em>÷</em><em> </em><em>Height</em>

<em>=</em><em> </em><em>90</em><em> </em><em>÷</em><em> </em><em>12</em><em>.</em><em>5</em>

<em>=</em><em> </em><em>7.2cm</em>

Artemon [7]
This is an unanswerable question there are no graphs for us to look at.

5x - 10y = -10
= (2, 2)
