Answer» -step explanation:Step-by-step explanation:Midpoint Theorem:The line segment joining the midpoints of two sides of a triangle is parallel to the third side and also half of it .GIVEN :In ∆ABC , AB = 5 cm ,BC = 8 cm,and CA = 7 cm ,D and E are respectively the midpointsof AB and BC .DE = \frac{1}{2} \times ACDE= 21 ×AC= \frac{1}{2} \times 7= 21 ×7= 3.5 \:cm=3.5cmTherefore.,\red { LENGTH \: of \: DE } \green {= 3.5 \:cm }LengthofDE=3.5cm✍️✍️✍️Mark my answer as brainliest mate |
