The arena will also have a children’s assault course in one area. as part of this, a climbing structure needs to be built in the shape of a pyramid. look at the diagram below.
what is the area of this shape?
m2

Area of the shape is 21 m².

Step-by-step explanation:

From the given figure it is clear that the figure contains one square with edge 3 m and 4 congruent triangles with base 3 m and height 2 m.

The area of a square is

The area of square is 9 m².

The area of a triangle is

The area of a triangle whose base is 3 m and height 2 m is

The area of a triangle is 3 m². So, the area of 4 triangles is

The area of 4 triangles is 12 m².

The area of shape is

Therefore the area of the shape is 21 m².

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
