b) Find the measurements of a rectangk with a perimeter of

26cm and an area of 1600cm​

There is no way to get an area of 1600 cm using a perimeter as small as 26 cm.

Step-by-step explanation:

perimeter = 2(L + W) = 26, then L + W = 13, so L = 13 - W

area = L x W = 1600

substitute for L:

(13 - W)W = 1600

13W - W² = 1600

-W² + 13W = 1600

-W² + 13W - 1600 = 0

W² - 13W + 1600 = 0
