Answer:
27 units (whatever units the figure was measured in)
Step-by-step explanation:
Answer:
An algebraic expression is an expression built up from constants,variables, and the algebraic operations.for example:3x^2-2xy+c is an algebraic expression.
> your welcome :) and tell me if it’s right
What does it say 3.5 or 3.50
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>
