Answer 1

210 yd²

Explanation:

If we rotate the shape we get a right angle triangle with a hypotenuse of 29 yd :

The area of a right angle triangle is given by the formula :

A =
`(ab)/(2)`

Substituting the 2 values given in diagram gives us :

A =
`((20)(21) )/(2)` = 420÷2 = 210

Our units will be yd² as we are dealing with area
