Can somebody me with the math's questions on pythagoras theorem?

£47.4

Step-by-step explanation:

See the diagram of the trapezoid attached.

ABCD is the trapezoid having AB = 20 m, CD = 12 m and the inclined side BC = 17 m

Now, draw a perpendicular on AB from point C which intersects AB at E.

Now, EB = AB - AE = AB = CD = 20 - 12 = 8 m

Now, Δ CEB is a right triangle and CE² = CB² - EB² = 17² - 8² = 225

⇒ CE = 15 m.

Therefore, the area of the trapezoid is sq. meter.

Now, given that one can of weedkiller can covers 100 sq. meters and each can cost £19.75.  

Therefore, 240 sq, meters area will cost £(19.75 × 2.4) = £47.4 (Answer)

answer: i believe its b. if you sound out the sentences that sounds wrong.
