ABCD is a trapezium

Calculate the area of ABCD

This is answer for finding bottom right hand corner angle where 25cm total base length is given. Where given, 4cm height trapezium with central height and central right angle, same format question but different heights as seen here in answer.

Step-by-step explanation:

AD part length 1 = 8.5² - 4² = √56.25 = 7.5cm

AD part length 2= 25-7.5 = 17.5cm

AD part length 3= 17.5- 5 = 12.5

AD total length = 7.5+ 12.5 + 5 = 25cm

Area = 1/2 x12.5 x 4 = 25  

Scalene Triangle 4/12.5 = 0.3 × 4 = 1.2

CD length size = 12.5 ² + 4² = 156.25 + 16 √172.25 = c² = 13.12cm

13.2/12.5 = 1.056

1/2 12.5 = 6.25

1/2 13.12 = 6.51.

6.25+ 6.51 + 4 = 16.76

1.056 x 16.8

CDA angle = 17.7˚

step-by-step explanation:

i reviewed this question with a peer and teacher, seems to be correct, me later

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
