surface area is the area of all the faces on a shape so to speak.
2(120 x 110)=26,400
2(120 x 4)=960
2(110 x 4)=880
880+960+26,400=28,240
Surface area = 28,240
Since the dimension of the scale model is fourth of dimensions of the room, divide by 4 the given dimensions.
new dimensions:
= 18 ft / 4 = 9/2 ft
= 16 ft / 4 = 4 ft
The area is calculated by multiplying the dimensions,
Area = (9/2 ft)(4 ft) = 18 ft²
Therefore, the area of the scale model is equal to 18 ft².
Answer:
All squares are rectangles.
Step-by-step explanation:
A square is a rectange with equal-length sides.
A rectangle is a parallelogram with right-angle corners.
A parallelogram is a quadrilateral with opposite sides parallel.
A quadrilateral is any 4-sided plane figure, not necessarily convex. Sides are not necessarily parallel, nor are angles necessarily 90°.
Answer:
1, 3, 4
Step-by-step explanation:
Points N and K are on plane A and plane S
Point P is the intersection of the line n and line g
Points M, P, and Q are noncollinear
Hi there!
9 + 1/2 (7n - 26) - 8n
= 9 + 7n*1/2 - 26*1/2 - 8n
= 9 + 3.5n - 13 - 8n
= 9 - 13 + 3.5n - 8n
= -4 + 11.5n
Hope this helps!
