whats the length of the rectangle

Question

Carl was working on an art project. One portion of the design will call for a rectangle that is painted half white and half red along a diagonal, as shown below.

 

If the height of the rectangle is 30.2 cm and the area painted red is 758.02 cm², what is the length of the rectangle in centimeters?

Answer 1

758.2/30.2 = about 25.106 cm

length is about 25.1 cm

25.1 x 30.2 = 758.02

length is a tiny bit more than 25.1 cm

but round off to the same number of decimals as the the other given numbers

758.2 and 30.2 have only one digit to the right of the decimal point. They may

have also be rounded off.

Area of a rectangle= length times width
