The area of a trapezoid is found using the formula A=1/2h(b^1+b^2), where b^1 and b^2 are the parallel sides of the trapezoid an
OverLord2011 [107]

\bf \textit{area of a trapezoid}\\\\ A=\cfrac{1}{2}h(b_1+b_2)~~ \begin{cases} A=18\\ b_1=5\\ b_2=7 \end{cases}\implies 18=\cfrac{1}{2}h(5+7) \\\\\\ 18=\cfrac{h(12)}{2}\implies 18=6h\implies \cfrac{18}{6}=h\implies 3=h

Find the missing part. L=8, w=4, h=2. Find the diagonal of (d) of the retangular solid
marusya05 [52]

The diagonal of the rectangular solid is d=2 \sqrt{21}

Explanation:

The length of the rectangular solid is l=8

The width of the rectangular solid is w=4

The height of the rectangular solid is h=2

We need to determine the diagonal of the rectangular solid.

The diagonal of the rectangular solid can be determined using the formula,

d=\sqrt{l^{2}+w^{2}+h^{2}}

Substituting the values l=8, w=4 and h=2 , we get,

d=\sqrt{8^{2}+4^{2}+2^{2}}

Squaring the terms, we get,

d=\sqrt{64+16+4}

Adding the terms, we have,

d=\sqrt{84}

Simplifying, we have,

d=2 \sqrt{21}

Thus, the diagonal of the rectangular solid is d=2 \sqrt{21}
