alexandr402 [8]

Answer:

The area that she painted = 896 mm^2

Step-by-step explanation:

Given:

The given figure is a pyramid with square base.

Here we need to find the surface area of the figure that need to be painted.

Surface area of a square pyramid = (S×S) + 2×S×L square.units

Where, S = side of the base L = slant height of the pyramid.

Now we have to plug in the given values.

Here S = 14, L =25

Plug in these values into the formula

= (14*14) + 2*14*25

= 196 + 700

= 896 mm^2

The area that she painted = 896 mm^2

Hope this will helpful.

Thank you.

Step-by-step explanation:

Given,

Length of rectangular backyard = 8 cm

Width of rectangular backyard = 4 cm

Real length of backyard = 8*1.5 = 12 m

Real width of backyard = 4*1.5 = 6 m

Real area of backyard = Length * Width

Real area of backyard = 12*6 = 72m²

The area of real backyard is 72 square meters.
