Find the area and the perimeter.

Find The Area And The Perimeter class=

Sagot :

Answer:

Area =910    Perimeter = 14 units

Step-by-step explanation:

Area is the inside measurement: A = L× W

The area of the whole rectangle - the white section = the area of the blue section

     Whole   -   the white

       rect.          rect.

A = (L x W)   -  (L x W)

A =  ( 20 × 50) - (6 × 15) = 1000 - 90 = 910 sq. units

Remember that perimeter is the distance around the figure: P = 2L + 2 W

Perimeter =  perimeter of the whole rect. - the perimeter of the white section.

Perimeter = 2(L) + 2(W)  - 2(L) + 2 (W)

                    2(50) + 2(20) - (2(6) + 2(15))

                        (100 + 40)  - (12 + 30)    

                                    140 - 36        

                                       104
