Answer and explanation:

Take the area formula:

A = L * W

Then manipulate it to fit the context of which unknown you are finding:

Problem 1


(36 = 4 * W)/(4)


9 = W

So, the length of side c is 9 mm.

Problem 2


(21 = W * 21)/(21)


1 = W

So, the length of side a is 1 m.

Problem 3


(49 = 7 * W)/(7)


7=W

So, the length of side t is 7 cm.
