Solve شبه منحرف بقاعدتين 5 و8 وارتفاع 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

مساحة شبه المنحرف: $A = \tfrac{1}{2}(b_1 + b_2) h$ .
عوّض $b_1 = 5$ ، $b_2 = 8$ ، $h = 4$ : $A = \tfrac{1}{2}(5 + 8)(4) = \tfrac{1}{2}(13)(4)$ .
بسّط: $A = 26$ .

Answer

$A = 26$
