answer for the 1st question:
1) length is 15 ft
2) width is 6ft
3) the area is 90 ft²
step-by-step explanation:
ok so we know that the plan is 2 in/6 ft
step 1-
we need to find the length of the terrace, and we know that the length of the terrace in the plan is 5 in
so by proportion- we'll need to find the length of the 'actual' terrace
2 in/ 6 ft= 5 in/ x ft
x=6*5/2
x=15 ft (we now have the length)
step 2-
now that we know the length, we need to find the width
the length of the terrace in the plan is 2 in
and by proportion- we'll find the 'actual' width of the terrace
2 in/6 ft=2 in/ x ft
x=6*2/2
x=6 ft
and now we'll find the area of the terrace (step 3)-
the formula for the area of a rectangle is a=lw or area=length*width
now we just fill the variables in with what we know-
so we know that 15 ft is the length and that 6 ft is the width-
15*6=90 ft²
**sorry about my original answer i didn't pay close enough attention**
good luck :)
i hope this helps
have a nice day !!
