The area of a triangular block is 16 squre inches. If the base of the triangle is twice the height, how long are the base and th
klemol [59]
The area of a triangle can be calculated using the formula 

1/2 (base) (height)

Let's substitute our known values, letting x represent the value of the height of the triangle.

16  = 1/2* x* 2x

Let's Simplify!

16 = x^2

Finally, lets take the square root of both sides, to get rid of the exponent on the right side of the equation.

x= positive OR negative 4.

However, because x is equal to the height, we know that it can't be negative, so we know that it is positive 4.

The height of the triangle = 4 inches
The base of the triangle = 2h = 8 inches

A contractor is hired to build an apartment complex. Each 840-square-foot unit has a bedroom, kitchen, and bathroom. The bedroom
Dennis_Churaev [7]

Answer:

350 sq ft

Step-by-step explanation:

Given that:

840 sq ft area has a bedroom, kitchen and bathroom.

Let the area of bedroom be x sq ft.

Then the area of kitchen will also be x sq ft.

Let the area of bathroom be y sq ft.

As per question statement:

x+y+x=840\\\Rightarrow 2x+y=840 ...... (1)

Tiles ordered to cover two kitchens and two bathrooms is 980 sq ft.

i.e.

2x+2y=980 ..... (2)

Subtracting equation (1) from (2):

i.e. (2) - (1):

y = 140 sq ft

Putting the value of y in (1):

2x+140=840\\\Rightarrow 2x =700\\\Rightarrow \bold{x=350\ sq\ ft}

Therefore, the carpet needed for each bedroom = <em>350 sq ft</em>
