Answer:
One
Step-by-step explanation:
First, we need to check a triangle with these sides <em>is</em> possible. Since 4 plus 5 is 9, and 9 is less than 10, we can make a triangle with these sides.
To answer the question, we can only make one unique triangle. Why? They give us three lengths and a triangle has three sides.
<em>However</em>, if they are counting a triangle in different positions the answer will be greater. Since it would just be the same triangle, I am going with the answer of only one.
If Mercedes alone could paint the house in 8 hours, we would expect that both painting together would take less than 8 hours.
In 1 hour: Dorie would paint 1/12 of the house, while Mercedes would paint 1/8. This is a total of 1/12 + 1/8 = 5/24. If they can combine to paint 5/24 of the house in 1 hour, then the total time for the whole house would be
1 / (5/24) = 24/5 = 4.8 hours or 4 4/5 hours
It has all angles measuring 60°

Answer:
(a) = 71 cm
(b) = 89 cm
Step-by-step explanation:
(a.)
perimeter of a rectangular field = 324 m
length (l) = 91 m
width (w) = ?
Now,
<em>Perimeter Of Rectangle </em>
<u>= <em>P = 2(l + w)</em></u>
= 2(91 + w) = 324m
= 182 + 2w = 324m
= 2w = 324 - 182m
= 2w = 142m
= w = 142/2
= w = 71
(b.)
area of rectangular painting = 5696 cm²
width (w) = 64 cm
length (l) = ?
Now,
<em>Area Of Rectangle </em>
A = <em><u>l × </u></em><em><u>w</u></em>
= l × 64 = 5696
= l = 5696/64
= l = 89 cm
<h2>
<em><u>VERIFICATION</u></em><em><u>:</u></em><em><u>-</u></em></h2>
FOR (a)
= P = 2(l + w)
<em><u>= P = 2(91 + 71) = 324 cm</u></em>
FOR (b)
= l × w
A = 89 × 64 = 5696
