Find the height of the triangle if the area is 36 m 2

n200080 [17]

Answer:

Area=1/2bh

Given area of 36m^2

1/2(x)(x-1)=36

Multiply both sides by 2 to remove deminator

(x)(x-1)=72

X^2-x=72

X^2-x-72=0 then factor

(x-9)(x+8)=0

X=9,-8 however since area must be positive, take the absolute value of 8

1/2(9m*8m)=36m^2

mina [271]

Answer:

Total space needed is 3136 square feet.

Step-by-step explanation:

We are given the following in the question:

Space required for eight manufacturing processes and six stockpiles.

Each takes 160 square feet.

Space required for 8 process =

$=8\times 160\\=1280\text{ square feet}$

Space required for 6 stockpiles =

$=6\times 160\\=960\text{ square feet}$

Total space =

$=1280 + 960\\=2240\text{ square feet}$

Open space required = 40%

$=\dfrac{40}{100}\times 2240\\\\=896\text{ square feet}$

Total space required =

$=2240 + 896\\=3136\text{ square feet}$

Thus, total space needed is 3136 square feet.
