Can someone solve this ~ similar shapes

first you need to find the length scale factor which is 15 ÷ 12 = 1.25

then to find the area of shape B u times the area of Shape A by 1.25^2

200 × 1.25^2

the area of shape b is 312.5 cm^2

(use a table to lay out ur working out if u want)

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
