Solve trapesium dengan sisi sejajar 5 dan 8, tinggi 4 — A = 26

Problem

$A = \tfrac{1}{2}(b_1 + b_2) h,\ b_1=5,\ b_2=8,\ h=4$

Step-by-step solution

Luas trapesium: $A = \tfrac{1}{2}(b_1 + b_2) h$ .
Substitusikan $b_1 = 5$ , $b_2 = 8$ , $h = 4$ : $A = \tfrac{1}{2}(5 + 8)(4) = \tfrac{1}{2}(13)(4)$ .
Sederhanakan: $A = 26$ .

Answer

$A = 26$
