Answer 1

Answer:

hey here is your answer

pls mark it as brainliest

so here we go

Step-by-step explanation:

now dimensions for jib are 10ft 8ft and 6ft

so as it is in form of scaled triangle

it's semiperimeter =a+b+c/2

where a,b and c are its three sides

so semiperimeter ie s=10+8+6/2

ie 24/2

so s=12 cm

now use herons formula ie

area of jib=

$\sqrt[?]{s(s - a)(s - b)(s - c)}$

so substitute values of s a b and c values in formula

you get

$\sqrt[?]{12 \times 2 \times 4 \times 6}$

=

$\sqrt[]{576}$

so ie nothing but 24 sq.ft

hence option c is right
