For prisms, use the formula: 2B + Ph

B = base of figure, here it is the trapezoid.
The area of the trapezoid is (3+6)*4/2 = 18

P = perimeter of the base, which is 3+4+5+6 = 18
h = height, here it is 5.

Thus the answer is:
2*18 + 18*5 = 36 + 90 = 126 cm^2

Please help me find the same denominator
Lelechka [254]

Answer:

\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}

let us first start with some basic information ~

A fraction can be represented as \frac{x}{y}\\ where ,

x is the numerator and y is the denominator !

the question asks us to do something that will help us get same denominator for both the terms !

so let's see what we should do in such a case ~

\frac{9}{10}  \: and \:  \frac{7}{8}  \\ \\ \\ lets \: make \: the \: denominator \: of \: both \\ the \: terms \: reach \: 80 \: , \\  \\ \bold\orange{ \implies \: \frac{9}{10}  \times  \frac{8}{8}  = }\bold\red{ \frac{72}{80}}  \\  \\\bold\orange{ \implies \:  \frac{7}{8}  \times  \frac{10}{10}  =}\bold\red{  \frac{70}{80}}

and we're done !

let's add some more info to be lil more clear ~

while converting the denominator of both the terms , we must multiply the same number ( this number refers to the one we'll have to multiply to the denominator to obtain the desired result ) with the denominator as well as with the numerator !

hope helpful :D
