been good, how has yours been?
Answer: 56 inches
Step-by-step explanation:
Given that:
Area of square frame = 196 in²
Area of a square = a²
Where a = side length
Hence side length (a) of the square :
a² = 196
a = √196
a = 14
To find the length of the ribbon required :
Find the perimeter of the square :
Perimeter of a square = 4a
= 4 * 14
= 56 inches
Answer:
17.5
Step-by-step explanation:
<u>Given</u>:
Given that the triangle with ∠B = 45°
The length of the side a is 4 units.
The length of the side c is 8 units.
We need to determine the area of the triangle.
<u>Area of the triangle:</u>
The area of the triangle can be determined using the formula,

Substituting a = 4, c = 8 and ∠B = 45° in the above formula, we have;

Simplifying, we get;



Thus, the area of the triangle is 11.31 square units.
