Answer:
56 m²
16 m²
88 m²
Step-by-step explanation:
The formula for the area of a rectangle is:
A=L×W (area=length × width)
A=7×8
A=56m²
The formula for the area of triangle is:
1/2×b×h (1/2 × base × height)
A=1/2×4×8
A=2×8
A=16m²
For the total area you will now add the area of each shape. We will multiply triangle area by 2 because there is 2 triangles.
A=56+2(16)
A=56+32
A=88m²
Answer:$590
Step-by-step explanation:
500*6%=30
30*3=90
500+90=590
Answer:
Step-by-step explanation:
sin(-430)=-sin(430)=-sin(360+70)=-sin 70
Equilateral means that the 3 sides are equal length. For this to happen, the triangle needs to also have 3 equal angles, but it is mentionned that it has an obtus angle, therefore, not all angles are the same, meaning the 3 sides also aren't equivalent.
the triangle isn't equilateral
Answer:
B. 104
Step-by-step explanation:
Just find the area of the wall and subtract the area of the window. The area of the wall is 10 times 11 which is 110. The area of the window is 2 times 3 which is 6. 110 minus 6 is 104.
