Answer:
7+<u>21</u>+15+19+.....+79
Here 21 be replaced by <u>11</u>.
Now., common diffrence btw terms , d = 11-7 = 4
first term , a = 7
Last term , l = 79
number of terms = ( a + l ) ÷ d
=( 7 + 79 ) ÷ 4 = 86 ÷ 4 = 21.5 { It cannot be in decimal }
<u>There's some mistake in the terms you provided please check your question again...</u>
A = b x h x 1/2
a = 30 x 31.5 x 1/2
a = 15 x 31.5
a = 472.5
