Answer:
4,257 m²
Step-by-step explanation:
step 1
Find the lateral area of the rectangular prism (ottoman)
The lateral area is
LA=PH
where
P is the perimeter of the base
H is the height of the prism
Find the perimeter of the base P
P=2(37+21)=116 cm
we have H=30 cm
<em>Find the lateral area</em>
LA=116(30)=3,480 m²
step 2
Find the area of the top of the ottoman
B=37*21=777 m²
step 3
we know that
The fabric needed to cover the sides and top of the ottoman is equal to sum the lateral area plus the area of the top
3,480+777=4,257 m²
Answer:
son age: X
man_age= 5X
in 3 years: we have: (man_age+3)(X+3)=380
we can replace the man age by 5X and we get :
(5X+3)(X+3)=380
it is a quadratic equation with 2 solutions. One negative and 7
The solution is thus 7, since age can not be negative.
The son is thus 7 and the dad 5 times more 35
Step-by-step explanation:
