(9+3)x7 is equal to 84
9+3=12
12*7=84
Answer:
see explanation
Step-by-step explanation:
The perimeter of a rectangle = 2l + 2w ( l is length and w is width )
given w = 63, then
2l + (2 × 63) = 324
2l + 126 = 324 ( subtract 126 from both sides )
2l = 198 ( divide both sides by 2 )
l = 99 m ← length of garden
-----------------------------------------------------------------
The area of a rectangle = lw ( l is length and w is width )
given l = 94, then
94w = 5828 ( divide both sides by 94 )
w = 62 cm ← width of window
Answer:
<h2>The perimeter of the cross section is 30 centimeters.</h2>
Step-by-step explanation:
In this problem we have the intersection of a rectangular prism an a plane.
The dimensions of the rectangular plane are
![l=12cm\\w=6cm\\h=9cm](https://tex.z-dn.net/?f=l%3D12cm%5C%5Cw%3D6cm%5C%5Ch%3D9cm)
Assuming the plane is cutting the prism horizontally, the cross section would have dimensions
![w=6cm\\l=9cm](https://tex.z-dn.net/?f=w%3D6cm%5C%5Cl%3D9cm)
Because only the height would be cut.
So, the perimeter of the rectangle cross-section is
![P_{cross}=2(l+w)=2(6+9)=2(15)=30cm](https://tex.z-dn.net/?f=P_%7Bcross%7D%3D2%28l%2Bw%29%3D2%286%2B9%29%3D2%2815%29%3D30cm)
Therefore, the perimeter of the cross section is 30 centimeters.
