Identify the area of the rhombus.

The figure shows a rhombus. The length of the shorter diagonal is x minus 4 meters. The length of the longer diagonal is 2 times x plus 4 meters.

A = (x2 − 16) m2
A = (x2 − 4x − 8) m2
A = (2x2 − 4x − 16) m2
A = (x2 − 2x − 8) m2

step-by-step explanation:

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242
