Take 7 divided by all the rest added up
The measurements are:<span>
b</span>₁ = 8.4 inches; b₂ = 14 inches; leg₁ = 2.8 inches; leg₂ = 2.8 inches<span>
Let x = length of base and leg
The formula for perimeter of isosceles trapezoid is P = b₁ + b₂ + 2(leg)</span><span>
Where: b = base
<span> P = b</span>₁ +
b₂ + 2(leg)</span><span>
<span> 28 = 3x + 5x + 2(x)</span>
<span> 28 = 8x + 2x</span>
28/10 = 10x/10
<span> 2.8 = x</span>
Now, substitute the values:
<span> P = b</span>₁ +
b₂ + 2(leg)</span><span>
<span> 28 = 3(2.8) + 5(2.8) + 2(2.8)</span>
28 = 8.4 + 14 + 5.6
28 = 28
Hence the measurements are:
b₁ =
8.4 inches; b₂ = 14 inches; leg₁ = 2.8 inches; leg₂<span> =
2.8 inches</span></span>
<span>7 x 7 = 49 area of square.</span>
<span /><span> The radius of the circle is half the diameter. 7 cm/2 = 3.5 </span>
<span> A = 3.14 × 3.5 cm × 3.5 cm = 38.465</span>
Finale step. Subtract the area of the circle from the area of the square.
49 cm^2 −38.465 cm^2 = 10.535 or round to 10.54 cm^2
