Need help figuring this out!
Ulleksa [173]

For this case, we have that by definition, the area of a triangle is given by:

A = \frac {b * h} {2}

where:

b: It's the base

h: It's the height

In this case we have:

b = 21 \ ft\\h = 6 \ ft

Substituting:

A = \frac {21 * 6} {2}\\A = 63 \ ft ^ 2

Answer:

63 \ ft ^ 2

Sara owns 3/4 of an acre of land. She wants to sell 5/6 of it. What fraction of an acre does she want to sell?
astraxan [27]

Answer:

5/8

Step-by-step explanation:

Sara owns 3/4 of an acre of land. She wants to sell 5/6 of it. What fraction of an acre does she want to sell?

The fraction of the acre of land that Sara wants to sell is calculated as:

= 5/6 of 3/4 of an acre of land

= 5/6 × 3/4

= 5/8 of an acre of land

Therefore, the fraction of an acre that she wants to sell = 5/8

in parallelogram abcd angle b is a right angle determine whether the parallelogram is a rectangle if so by what property​
Digiron [165]

Answer:

If a parallelogram has at least one 90 degree angle then its opposite angle is equal and also = 90 degrees.  

The 2 remaining opposite angles add up to 180 degrees and since they must be equal, they must be 90 degrees each.

So, we have a quadrilateral with four 90 degree angles and is therefore a rectangle OR it could possibly be a square.
