First solve the length of side BC, CD, EF and FA
Since BC = CD = sqrt( 10^2 + 10^2)
BC = CD = 14.1421
FA = EF = sqrt(10^2 + 20^2)
= 23.3607
So the perimeter = 10 + 10 + 14.1421 + 14.1421 + 23.3607
= 93
The area is made up be triangle FAE, rectangle ABDE and
triangle BCD
A = 0.5(20)(20) + (10)(20) + 0.5(20)(10)
<span>A = 500 sq units</span>
Since you know what 4×5 is you just have to use the same answer
The answer is 100,000
<span>In order to answer this, you must got to the number in the hundred thousand spot, in this case 1, and the check the number next to it. If it is 5 or more, the number becomes bigger, and if it is less than 5, you keep the number the same. After this, any numbers to the right become zeros. </span>
Answer:
1.thursday
his expenses was p26.85
2.monday he spent p40.8
3.18.90+23.15+11.80+16.35+9.20=approximately p55.6×30 days=p1,668
4.693.80-1,668
so he savings is completely enough
