plz help plz help me plz help me plz help me I don't want to get grounded the whole summer the question is. the window has the shape of a kite how many square meters of glass were used to make the window? ​

648 cm ²

Step-by-step explanation:

Lets solve each triangle 1-by-1.

Note that the area of a triangle is: · l · h

· 18 · 15 = 135 cm

· 18 · 15 = 135 cm

135 + 135 = 270 cm

· 21 · 18 = 189 cm

· 21 · 18 = 189 cm

189 + 189 = 378 cm

378 + 270 = 648 cm ²

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
