Answer:
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
