Answer:

A= 145.12mm^2

Step-by-step explanation:

The diagram shows us a Right angle triangle; so, I use Phythagoras' Theorem, to find length of the base.

c^2 - b^2 = a^2

27^2-12^2 =a^2

585. = a^2

Square root both sides

a = root 585

= 24.18677324

A= bxh/2

= root 585 x 12/2

= 18 root 65

= 145.1206395

A= 145.12mm^2 to 2.d.p

(Haven't rounded up in calculations until the end. Thus, using the exact values of root 585,for example. )

Hope this helps!
