Question

The area of a rectangular field is equal to 300 square meters. Its perimeter is equal to 70 meters. Find the length and width of this rectangle​

Answer 1

Answer:

3x + 4 = 133x+4=13

3x = 13 - 43x=13−4

3x = 93x=9

x = \frac{9}{3}x=

3

9

x = 3x=3

Answer 2

Answer:

Answer W = 15 and L = 20

L × W = 300 : area , L is the length and W is the width. 2 L + 2 W = 70 : perimeter L = 35 - w : solve for L (35 - W) × W = 300 : substitute in the area equation W = 15 and L = 20 : solve for W and find L using L = 35 - w.
