Find the surface area of the pyramid

Mathematics
1 answer:
Tcecarenko [31]3 years ago
6 0

Answer:

2100

Step-by-step explanation:

Surface area is the area of all the sides

The area of the rectangular base is W x L =  30 x 30 = 900

Then to find the area of the triangles its \frac{1}{2}bh

A = \frac{1}{2} 30 x 20

A = \frac{1}{2} 600

A = 300

Since there are 4 triangle faces on a pyramid we times 300 x 4 = 1200 is the area of all the triangles

Then we add the area's

1200 + 900 = 2100

Sorry if its wrong

Julli [10]

Answer:

600 sq mm

Step-by-step explanation:

I divided the shape into 2 shapes and found each shapes area and after that added both of its area to find the area of the above shape

area of rectangle= b x h

so, 15x30=450mm (square)

area of triangle= b x h (divided) 2

so, 10x30=300 (divided) by 2

= 150mm (square)

so, 450 (plus) 150= 600mm (square)

Step-by-step explanation:

If the scale factor is 2/7 divide 12 by 2 which is 6. 6 is 1/7 and if Figure a is 7/7

multiply 6 by 7 to get x. That would be 42.
